WASHINGTON (AP) — The loud, insistent calls in Washington to rein in the rising costs of Social Security and Medicare ignore a major and expensive entitlement program — the military's health care system. Despite dire warnings from three defense secretaries about the uncontrollable cost, Congress has repeatedly rebuffed Pentagon efforts to establish higher out-of-pocket fees and enrollment costs for military family and retiree health care as an initial step in addressing a harsh fiscal reality. The cost of military health care has almost tripled since 2001, from $19 billion to $53 billion in 2012, and stands at 10 percent of the entire defense budget. Even more daunting, the Congressional Budget Office estimates that military health care costs could reach $65 billion by 2017 and $95 billion by 2030.
